Lady Gaga rocked the BBC's Children in Need concert tonight (November 17) organised by X Factor judge and mentor, Gary Barlow.

Introduced by Neil Tennant, Fearne Cotton and Chris Moyles, Gaga started with 'Born This Way'. The singer then performed her new single,'Marry The Night'.

Gaga wore a classic '50s style backless black outfit, black gloves, pearls, red lipstick and Marilyn Monroe-esque curls. She then removed the lower half of her outfit to reveal fishnet stockings.
